The Houston Astros named Tony DeFrancesco as their interim manager after dismissing manager Bradley Mills Saturday, Aug. 18. DeFrancesco was managing Triple-A Oklahoma City. General manager Jeff Luhnow will spend the next few weeks searching for a full-time replacement. Houston already has four or five names in mind, and they're hoping to have a new candidate in place by Nov. 1. Minor league hitting coordinator Ty Van Burkleo was named as the interim hitting coach and Dan Radison will be the interim first base coach.
